How to create reversed cost through import from third party ?

Summary:

Generate reversed costs

Content (required):

Hi,

We need to create reversed costs.

Is there any document that describes what exact fields should be populated in the costing interface, so we can create/generate reversed costs?

I tried to populate same fields as on the initial transaction/cost, of course quantity negative, but system gives "Transaction already exists" error. Even if I provided the reversed_orig_txn_reference...

Kind regards,

Elena
